Measuring Ranges; Measuring Accuracy - RMG TME400-VMF Operating Manual

1 Introduction
1.4.2.8.
Type TME400 turbine meters have measuring ranges of at least 1:20 at atmospheric
pressure (see chapter 1.4.2.9 Measuring accuracy). At a higher pressure, the meas-
uring range can be expanded to 1:50. The measuring ranges are between 2.5 and
25,000 m

Note
With a slightly smaller measuring range of 1:16, turbine meters are also
available in nominal diameters DN 80 and DN 100, which have an increased
accuracy with a deviation of max. ±1% in the range of 0.2 x Q
